This is a digital file. May I print it?
While intended to be a digital resource, it can also be printed. To do so, go to File > Print > Lay Out > Pages Per Sheet > 2 or 4 > Print. 2 to a page prints with awkward margins but are easier to read and write directly on. 4 to a page prints in perfect task-card form (the size of post cards).
How Do I Use These for a Whole-Class Number Talk?
Using Google Slides you are able to display these prompts. If you download the Page Marker Google Chrome extension, you can write directly on the slides (no log-in required) in different colors. Using an Interactive Whiteboard, you can use the markers or your finger to write on top of these images/slides. If using a touch-screen Chromebook or iPad, you can use a stylus to record students’ thinking. Should you want to rock a low-technology option, display the prompt on a screen and record student thinking on anchor chart paper, a white board, or an easel.
Can I share this with students?
Yes! On a password-protected site or platform, you are welcome to share this digital file with students and families. That might look like a Google Classroom, a password-protected website, a password-protected Flip Grid, See Saw, etc. Due to copyright, the digital file may not be placed on a class website that is accessible to the general public. Have questions? Ask a Q&A on Teachers Pay Teachers, and I’m happy to answer!
With what programs is this compatible?
This digital file is able to work with GoogleTM Slides, Google Drive, SeeSaw. Microsoft OneDriveTM, or Pic Collage. Note – In SeeSaw, the interactive pieces do not work. Then students may submit their thinking digitally. For instructions on how to use this resource with Microsoft OneDriveTM and SeeSaw visit bit.ly/digitalinstructions
Can I share just one or a few prompts at a time?
After you make a copy of this digital file and add it to your Google Drive, you are free to manipulate the slides. You can add/delete/or move around the pages to meet the needs of your students. Only want to share one prompt? Perfect. Delete the other slides and share the file via Google Classroom for your students. Then, when you want the rest of the tasks, you can come back to this link and reopen the original file.
Happy Teaching,
Catherine – The Brown Bag Teacher

These number talks were fantastic for building my students’ number sense. It was eye-opening how difficult they were for some of the students who are used to being able to procedurally add numbers without really understanding the logic behind “carrying” a one and so on.

I really love how I can use base ten blocks to model what happening with each type of regrouping.
